Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image data collection device and system applied to a navigation device that displays a map in an automobile, a portable terminal device, or the like.
[0002]
[Prior art]
Conventionally, various types of navigation systems have been developed with a focus on car navigation devices mounted on automobiles. In recent years, in addition to this, opportunities for humans to carry portable information terminals have increased, and the demand for map information has increased accordingly. On the basis of such a background, not only simple two-dimensional map information so far but also demand for three-dimensional expression is increasing from the viewpoint of easy viewing and easy understanding.
[0003]
However, for this purpose, creating and maintaining a three-dimensional map one by one is an enormous work. In order to avoid this, it is most preferable to take an image of a desired point and paste it directly on the map. In recent years, it has become possible to easily connect to the Internet from the above-described car navigation system, portable terminal, etc., and a desired image can be read out from a server storing captured image information as described above and immediately displayed on the screen. It is also possible easily.
[0004]
Furthermore, when high-speed packet communication by IMT-2000 (next generation mobile communication service) is started, not only such three-dimensional data but also transmission of moving images can be displayed in real time.
[0005]
In addition, in May 2000, a positioning system using a GPS satellite has an unprecedented infrastructure for navigation, such as an error of about 1 m.
[0006]
As a method for collecting a photographed image in this manner, Japanese Patent Application Laid-Open No. 11-160080 discloses a system that collects a photographed image by linking a car navigation device and an imaging means provided in an unspecified number of moving vehicles. Yes. Since the captured image is immediately stored in a database in the information center through a communication line, various images can be collected efficiently.
[0007]
[Problems to be solved by the invention]
As can be inferred from what has been explained so far, in providing 3D map information, even if the photographed image is simply pasted on the screen, it is enormous if it corresponds to a national map. It is necessary to take a number of images. On the other hand, if you try to provide detailed images even if you try to respond even in urban areas alone, the number of shooting locations will also be enormous, and it will be very difficult to maintain and manage the system Will be a difficult task.
[0008]
For this reason, if a system such as that described in Japanese Patent Application Laid-Open No. 11-160080 is to be adopted, a great deal of labor must be spent on control of an unspecified number of vehicles, organization of captured images, and the like. In addition, since the general vehicle has a low vehicle height, if the vehicle is preceded by a large vehicle, the field of view is interrupted and the number of unusable images increases.
[0009]
The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a system that automatically captures an image of a predetermined point periodically without the driver of the moving vehicle being conscious. .

[0038]
DETAILED DESCRIPTION OF THE INVENTION
Next, a preferred embodiment according to the present invention will be described. FIG. 1 is a block diagram for explaining an automatic image data collecting apparatus of the present invention. In FIG. 1, when the main switch S1 is turned on, power is supplied to the main part of the apparatus from the power supply unit 110 constituted by a rechargeable battery such as lithium ion, and operation starts. First, a memory card (not shown) in which shooting point data has been recorded in advance is inserted into the shooting point input unit 103, and information in this card is recorded in the RAM 104. The CPU 102 compares the output position data from the position detection unit 101 that receives the signal from the GPS satellite and detects and outputs the current position, and if the radius is within 500 m from the planned shooting point, the CPU 102 , 106 and a switch S3 for supplying power to the transmission unit 108 are turned on, and a command to start photographing is given to the imaging units 105 and 106.
[0039]
The images captured by the imaging units 105 and 106 are once recorded in the image recording unit 107, and if the connection with the center is confirmed by the transmission unit 108, the previously recorded image is transferred from the transmission unit 108 to the center. To do. A series of these sequences is programmed in the ROM 109. Further, when the card is read or while the movement is stopped, the operation button 112 can be operated on the display unit 111 to check the remaining photographing position and the remaining battery capacity.
[0040]
FIG. 2 is a schematic external view of the automatic image data collection apparatus. 2, the GPS unit 201 corresponds to the position detection unit 101 in FIG. 1. Similarly, the transmission unit is the transmission unit 108, the imaging unit is the imaging units 105 and 106, and the power supply unit 208 is the power supply unit 110. The confirmation display 206 corresponds to the display unit 111, the operation button 207 corresponds to the operation button 112, the power button 209 corresponds to the switch S1, the control unit 204 includes the CPU 102, ROM 109, RAM 104, switches S2, S3, and image recording unit. 107 or the like. The attachment unit 210 is constituted by a powerful suction mechanism (not shown) for attaching the apparatus to the roof of the automobile.
[0041]
FIG. 3 is an explanatory diagram when the apparatus shown in FIG. 2 is actually attached to an automobile. As shown in the figure, a vehicle having a height as high as possible is preferable because the field of view is not obstructed during photographing. In FIG. 3, the automatic image data collection device 302 is fixed by a suction mechanism near the center line of the upper body of the collection / delivery vehicle 301. In this way, when the vehicle height is high and the overall length is long, the imaging portion 303 for rear photographing is fixed to the rear upper part of the vehicle body to prevent the view from being blurred. The image data photographed by the imaging unit 303 for rear photographing is sent to the automatic image data collecting device 302 by a cable or wirelessly such as Bluetooth. Of course, the rear imaging unit also has a suction mechanism, and a power source is built in.
[0042]
FIG. 4 is an explanatory diagram of a shooting location. In FIG. 4, a to j are scheduled shooting points, and the inside of a wavy circle surrounding it is a shooting area with a radius of about 500 m. Also, rectangular wavy areas A, B, and C represent delivery areas for home delivery. For example, when data on points a, b, and g is desired, the device may be set in a vehicle having A and C as delivery areas. At that time, if it was taken with two cars as passing points, it would be better to adopt a more preferable image. On the other hand, even if it did not pass the shooting point, when the original home delivery operation was completed, the image collecting work was also ended. By doing so, it is possible to collect images without placing any burden on the delivery service.
[0043]
Next, imaging and transmission of image data will be described based on the flowcharts of FIGS. Here, FIG. 5 is a flow for explaining the procedures of photographing and transmission, and FIG. 6 is a flow for a portion of the flow of FIG. 5 for transmitting image data. First, an automatic image data collecting apparatus in which a memory card in which data of shooting points is recorded is inserted into the shooting point input unit 103 (FIG. 2 card insertion unit 205) of FIG. 1 and the shooting points are written in the RAM 104 in advance. Is attached to the delivery vehicle as shown in FIG. Thereafter, the main power supply is turned on in step S501 in FIG. Since the main power is turned on, the automatic image collecting apparatus always measures its current position as shown in step S502.
[0044]
At this time, if the capture of a predetermined number of GPS satellites is sufficient and the latitude and longitude can be calculated, it is confirmed in step S503 that the transmitter is not turned on, and then the CPU 102 calculates the position. The data is transmitted, and if the transmission unit is turned on, it is confirmed that it is not in the middle of image transfer, and then the transmission unit is turned off (step S504). Is sent out (step S505). On the other hand, if the GPS satellite is not sufficiently captured due to a high-rise building or the like, the CPU 102 automatically turns on the switch S3 to supply power to the transmission unit (step S506). Here, by using a PHS having a structure capable of outputting the base station ID to the outside, the base station ID closest to the current position is acquired (step S507), and the position data is sent to the CPU 102 (step S507). S505).
[0045]
The CPU 102 compares the received position data with the photographing point data read in advance into the RAM 104, and determines whether or not the vehicle has reached a point within a radius of about 500 m (step S508). As a result, if it is determined that the vicinity of the photographing point has been reached, it is first determined in step S509 whether or not the power of the imaging unit has already been turned on. If the power of the image pickup unit has already been turned on, the process proceeds to the next step as it is, and if it has not been turned on, the switch S2 in FIG. 1 is turned on to turn on the power of the image pickup unit. Thereafter, in step S511, the current time is determined to determine whether it is daytime or nighttime. As a standard for this, it is preferable that the time from before and after sunset to before and after sunrise is regarded as night, and the time for comparison is preferably changed according to the season. As a result of comparison, if it is determined that it is daytime, the image is taken as it is in the next step S512, and if it is determined that it is nighttime, the gain of the imaging unit is increased in step S513, and the image is taken in step S512. The image data is temporarily recorded in the image recording unit 107 in FIG. 1 and, as will be described later, a recording end signal for the transmission unit 108 to prepare for transmission is output from the CPU 102 to the transmission unit 108. .
[0046]
The foreground and background imaging units are each used to complete one shooting, and based on the above-described recording end signal, a transmission operation described later is immediately started, and the process returns to step S502 and the current position is set again. taking measurement. As a result, if it has moved about 100 m from the previous photographing position, photographing is performed again. In this way, the image capturing is repeated, and if it is no longer near the predetermined position (within a radius of about 500 m) in step S508, the power supply state of the imaging unit is confirmed in step S514, and the switch S2 is turned off in step S515. Then turn off the power of the imaging unit. This completes the shooting for one scheduled shooting point. In the next step S516, it is confirmed whether shooting for all the scheduled shooting positions has been completed. That is the end of the shooting operation. If not completed, the process returns to step S502 and the current position is continuously measured.
[0047]
Next, a flow for transmitting captured image data will be described. In step S520, it is determined whether the above-described recording end signal is output. If the recording end signal is output, transfer of image data is started in step S521. A detailed flow of this transfer will be described later with reference to FIG. Further, in this step S520, in addition to the case where the above-mentioned recording end signal is output, the case where the transmission was previously cut off in the middle and the transmission of the image data has not been completed yet is left in the image data collecting apparatus. Also, this unsent remaining frame is automatically detected, and transmission is performed until there is no remaining frame in step S521.
[0048]
If there are no remaining frames in this way, it is confirmed in step S522 whether or not the line is connected. Normally, since transmission has been performed so far, the connected line is blocked in step S523, and the transmission unit The power switch S3 is turned off. The case where the connection is not established in step S522 is a case where the connection to the center server is not established even after dialing a predetermined number of times in step S521. Thereafter, in step S524, it is determined whether shooting at all scheduled shooting points has been completed. If shooting has not been completed, the process returns to step S520 and waits for a recording end signal to be output. If the photographing of all positions has been completed, the main power switch S1 is turned off (step S525), and the collection of image data is terminated. After that, after the collection and delivery work is completed, the image data collection device is removed from the moving vehicle, or a memory card in which new shooting point information is recorded is inserted into the card insertion unit 205, and information on the next shooting point is read into the device.
[0049]
Next, the transmission of the captured image data in step S521 will be described in detail with reference to the flow of FIG. First, in step S601, it is confirmed whether the transmission unit is turned on. If not, the switch S3 is turned on in step S602 to turn on the power of the transmitter, that is, the mobile phone or the PHS. Thereafter, in step S603, it is determined whether or not the connection with the center image collection server is already established. If the connection has already been established, transmission of image data is immediately started in step S604. If not yet connected, a call operation is performed to the center in step S605, and it is determined whether or not the connection is completed in step S606. If the connection is established, transmission of image data is started in the next step S604. In step S605, it is determined whether or not the line has been cut off until the transmission is completed. Complete the data transmission.
[0050]
Next, in this transmission operation, a case will be described in which the connection to the center is not successful or the connection is cut off during the transmission of image data. First, in step S605, the center is called, and if not yet connected in step S606, the process waits for a predetermined time in step S607, and returns to step S601. If the connection to the center is not established even after repeating this loop for a predetermined time, the call to the center is temporarily stopped in step S608 and the power of the transmission unit is turned off. Thereafter, in step S609, the number of redials at short time intervals is determined. If the number of redials is within a set number of times, for example, 5 times, the process waits for a short time to redial in step S610, and then returns to step S601. The waiting time is preferably about 3 to 5 minutes and the number of redials is about 5 times. This operation is repeated, and if the predetermined number of times (5 times) is exceeded in step S609, this time, after waiting for a long time interval, redialing is performed (S611). The long time interval is preferably about 30 minutes. When this time elapses, the subroutine is exited, and the process proceeds to step S520 in FIG. 5 to try to call the center again.
[0051]
On the other hand, if the transmission is interrupted for some reason before the transmission of one frame is completed in step S612, preparation for transmitting the same image data is performed again in step S613, and the process proceeds to step S609. Repeat the same redial loop as before. In this way, as long as the main power is turned on, the image data collection device is configured to try to transmit the photographed image data to the center. In case the camera cannot send all shot images to the center or connect to the center, insert a large-capacity memory card into the card insertion section and store unsent image data here. It is desirable to record, and after the day's collection and distribution work is completed, the memory card is taken out and untransmitted image data is read out at the center.
[0052]
The transmitted image data includes the shooting date and time, the shooting position, the foreground / background identification code, the shooting direction, and the like in addition to the shot image. As for the shooting direction, since a plurality of images are taken at one place in this embodiment, it is not necessary because the shooting direction can be understood by comparing the shooting positions, but only one shot is taken at one place. In such a case, it is necessary information. As a specific data format of the shooting direction, the moving direction from the shooting position and the previous position is determined, and this is, for example, 360 ° around the circumference, 8 east, west, south, north, east northeast, east southeast, etc. What is necessary is just to assign to the divided | segmented 2-bit code | symbol.
[0053]
In addition, it is easy for the driver to manually operate the remote controller or the like from the driver's seat so that the data collection apparatus can be photographed. Specifically, the CPU 102 receives step S509 and receives step S509. It may be configured to interrupt to start. Accordingly, it is possible to quickly respond to road information that has not been grasped in advance by the center and road information such as an unexpected disaster.
[0054]
In this embodiment, the method of installing this data collection device on the collection and delivery vehicle of a courier company that is deployed nationwide has been shown. However, as a contractor, there are other sightseeing buses, regular buses, and long-distance truck flights. As long as the daily travel route is clear and the vehicle height is higher than a certain level, the type of business is not limited.
